Carbon-coated SnO₂ riveted on a reduced graphene oxide composite (C@SnO₂/RGO) as an anode material for lithium-ion batteries.

ABSTRACT: The research on graphene-based anode materials for high-performance lithium-ion batteries (LIBs) has been prevalent in recent years. In the present work, carbon-coated SnO₂ riveted on a reduced graphene oxide sheet composite (C@SnO₂/RGO) was fabricated using GO solution, SnCl₄, and glucose via a hydrothermal method after heat treatment. When the composite was exploited as an anode material for LIBs, the electrodes were found to exhibit a stable reversible discharge capacity of 843 mA h g^-1 at 100 mA g^-1 after 100 cycles with 99.5% coulombic efficiency (CE), and a specific capacity of 485 mA h g^-1 at 1000 mA g^-1 after 200 cycles; these values were higher than those for a sample without glucose (SnO₂
